Operations
They entered "Hatsukari" intercity services in 1996. However, "Hatsukari" services were discontinued with the opening of the Tohoku Shinkansen extension to Hachinohe, and they entered "Hakucho" intercity services linking Hachinohe and Hakodate. At the opening of the Tohoku Shinkansen extension to Shin-Aomori, 4-car sets were used on "Tsugaru" intercity services linking Aomori and Akita. However, they used on "Tsugaru" services were eventually displaced with E751 series. At the opening of Hokkaido Shinkansen, "Hakucho" services were discontinued, and 485-3000 series used on "Hakucho" services were completely scrapped.
On the other hand, 2 nine-car sets of 485-3000 series including 2 saro481
vehicles entered "Hakutaka" intercity services linking Echigo-Yuzawa
and Kanazawa over the period from 1997 until 1998. 5 six-car sets also
entered for "Inaho" and "Hokuetsu" intercity services
over the period from 1996 until 2000. Train sets used on "Hakutaka"
intercity services were displaced with 683-8000 series in 2005 and converted
to 6-car train sets to enter "Inaho" and "Hokuetsu"

overturned by strong winds, and eventually scrapped. In addition, train

at the opening of the Hokuriku Shinkansen extension to Kanazawa. Finally,
485-3000 series vehicles used on rapid services linking Niigata and Itoigawa
were completely scrapped because rapid services were discontinued in 2017. |
